Well... yes, a "personalized train" would be so much more convenient. Then you could play games, text, talk, and sleep while you travel. All in the comfort of your own car. Frankly, since I tend to make long car trips, I can see the appeal!
S0nce I was a young girl I've thought that self-driving cars would lead to: less traffic, fewer accidents, better gas mileage. In my 9-year old mind, I had envisioned the major interstates runnning with tracks down each lane (kind of like the car wash), and you programmed in which exit you wanted to get off (this was long before 'wireless' technology). Then your car would be merged to that exit and set "free" when you got there. (Kind of like getting the rocket in Mario Karts...). At any rate, I am looking forward to seeing where self-driving cars go... no pun intended.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
